How data was acquired	MarqMetrix All-In-One Raman Spectroscopic Ball Probe
Data format	Baseline Subtracted, Normalized, and Averaged
Experimental factors	Five samples were collected for each experimental condition, each consisting of 20 averages of 1000 ms integration time. These five samples were then used to create a mean sample with PEAXACT (Aachen, Germany) quantitative spectroscopy software.
Experimental features	Formic acid was gasified in a continuous supercritical water reactor at temperatures from 300°C to 430°C, at residence times between 4 s and 65 s, at a constant pressure of 25 MPa, and with a constant initial formic acid concentration of 3.6 wt%. Spectra were collected in the cold zone of the reactor as described inRef. [1].
